Abstract: Apparatus and associated methods relate to a pneumatic distribution system having pneumatic pump that exhausts into a common plenum that is in fluid communication with a plurality of flow controllers. In an illustrative embodiment, a system controller may coordinate the operation of the one or more pneumatic pumps and the plurality of flow controllers to provide air pressure control to a system of pneumatic chambers. In some embodiments, one of the plurality of flow controllers may be configured to provide fluid communication with an ambient atmosphere so as to permit a fluid path from a pneumatic chamber connected to another flow controller to the ambient atmosphere via both flow controllers and the common plenum. In an exemplary embodiment, the system controller may advantageously control the air pressures in a plurality of pneumatic chambers independently of one another using coordinated control of the pump and flow controllers.

Abstract: Apparatus and associated methods relate to nutating a piston drive linkage oriented around a longitudinal axis in response to the rotation of a drive shaft about a drive axis, said longitudinal axis being offset and canted with respect to said drive axis. In an illustrative example, the piston drive linkage may be formed as a wobble plate extending radially from the longitudinal axis. Near a periphery, the wobble plate may attach to a plurality of stationary piston cranks. The nutating motion of the piston drive linkage may impart a substantially linear motion profile substantially parallel to the drive axis of rotation. A bearing oriented around the longitudinal axis may advantageously be freely inserted into and removed from an aperture in the wobble plate. An inner race of the bearing may freely rotate about the longitudinal axis in response to rotation about the drive axis.
